   Areas affected...Portions of northeast Colorado and northwest Kansas

   Concerning...Heavy snow 

   Valid 251352Z - 251645Z

   SUMMARY...Snowfall rates in excess of 1 inch per hour are possible
   across northeast Colorado and northwest Kansas this morning into the
   early afternoon.

   DISCUSSION...A band of snow has developed from northeast Colorado to
   northwest Kansas in a region of strengthening mid-level
   frontogenesis. Expect this band to reach peak intensity during the
   mid-to-late morning hours and persist into the afternoon. The
   dendritic growth zone is sufficiently deep and saturated and is
   located near the strongest ascent near the mid-level frontogenesis.
   This will support larger flake sizes which also assist in snowfall
   accumulation. Overall, snowfall rates are expected to be around 0.5"
   per hour, but greater rates at or above 1 inch per hour are
   anticipated in strong banding near the Colorado/Kansas border. A
   regional radar loop shows a stronger band extending from Washington
   County, Colorado to western Kansas. This may be the beginning stages
   of the stronger band of snow which is anticipated to develop by 15
   to 16Z.
